Planetarium of Saint-Etienne

The Planetarium of Saint-Étienne is a science center with a modern dome theater featuring digital projections that display celestial bodies and astronomical phenomena on its curved ceiling. The space is designed so visitors can experience the night sky from their seats as if observing it naturally.

The Planetarium was founded in the second half of the 20th century and developed into an important site for astronomical education in the Loire region. Since then it has equipped itself with modern technology to bring the study of stars closer to generations of visitors.

The facility draws school groups and families who gather to explore the night sky together and discover space topics. The shows are designed to inspire visitors of all ages and spark their curiosity about the cosmos.

The dome hall is accessible by wheelchair and seats can be adjusted so everyone can follow the show comfortably. It is recommended to reserve ahead of time, especially when visiting with school groups or larger families.

Visitors recline in adjustable seats while watching planets and star formations that seem to move above them in the dome. This position allows the sky to be experienced naturally, similar to lying on the ground looking upward.
